Norway trunnion cylinder

(Norway trunnion cylinder,produced by Hengyu Group)

trunnion cylinder are widely used in Norway,because of excellent temperature resistance,no need for deceleration device,long service life.So our company has designed trunnion cylinder for customers from Norway.

Introduction to trunnion cylinder:

When the trunnion cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the trunnion cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil trunnion cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical trunnion cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the trunnion cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

When the trunnion cylinder is customized, if there are high requirements for the quality of the trunnion cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the trunnion cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the trunnion cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

In order to ensure the service life of the trunnion cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the trunnion cylinder, causing damage to the seal and causing leakage in the trunnion cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

In the process of using the trunnion cylinder, sometimes such a problem will occur, the trunnion cylinder can not act immediately after the instruction of the trunnion cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil trunnion cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about trunnion cylinder:

The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.

How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
